REGISTER FOR HOT-AIR FUR-NACES.

Specification of Letters Patent No.

To all whom t may concern Be it known that I, CHARLES F. TUTTLE, ofWilliamsburgh, county of Kings, State of New York, have invented a newand Improved Method for Opening and Closing the Valves of Hot-AirRegisters and Ventilators; and I do declare the following to be a fulland exact description.

The nature of my invention consists in the new and improved method ofopening and closing the valves of hot air registers and ventilators bymeans of a slide piece placed either at the top or at one end of theregister the said slide piece being connected to the valves by means ofconnecting rods that work with a joint at their point of connection withthe slide. And also with a joint at their point of connection to thevalves. One end of the connecting rod moving in a circular directioncorresponding to the motion of the valves moved, constructed so as toseriously diminish the friction in opening.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation, reference being hadto the annexed drawings, in which- A Figure l is a perspective view, andFig. 2 a sectional view of one end containing the slide and apparatusfor moving the valves. Fig. 3 represents an arrangement for opening andclosing a register with three valves. My register is constructed as thevimproved styles of registers are with the top or front of open scrollor fret work. That part of the frame in which the valves are suspendedis far enough from the top or front to allow the valves to play freelyon their pins or axles, wit-houttouching the top of the register. Thetop or front part is usually made so that it can be taken off and readyaccess be had to the valves or working apparatus. The valves must beconfined at their pins or axle with clasps or otherwise, in a mannerthat will allow them to play freely, and yet prevent them from gettingo-ut of place. The slide piece is suspended at the side or end of theregister (c a representing the top of the register) (this slide 6,708,dated september 11, 1849.

piece may be placed at the top) and is suspended by the two pins orfixtures (l d, or otherwise, that will allow the slide to move withease.

f f, are the valve pieces which are used to shut off the current of airfrom passing through the register.

7c 7c are the connecting rods which join or connect the slide piece tothe valves, and through which the motion is imparted. At t-he point e atwhich the connecting rods join or connect to the slide piece is a joint,made by the rod working over a pin on the slide piece or otherwise. Alsoat the place where the connecting rods are connected to the valves asatg g, is a oint or joints, these joints allow the connecting rods toaccommodate themselves to the motion of the valves without binding andwithout much friction.

zA L are pieces or arms projecting from the surface or ends of thevalves to which the connecting rods are attached.

z' z' is the lower part of the frame in which the valves are suspended.

c is the small projection or knob at t-he surface of the register, bywhich the slide piece is moved and the valve set in motion. The mannerin which the motion is imparted from the slide piece, through theconnecting rods to the valves, may readily be seen by looking at Fig. 2.

Vhat I claim as my invention and desire to secure by Letters Patent, is

The combination'of the slide piece and the connecting rod or rods forthe opening and closing of hot air registers and ventilators, the saidconnecting rod or rods being so joined to the slide piece as to form ajoint at the place of connection, the said connecting rod or rods alsoforming a joint at their point of connection to the valves or armsthereof, causing the end of the rods joined to the valves to move in acircular direction, corresponding to the motion of the valves whenmoved.
